tThe present invention has relation to .nia-

A chilies for forming eaves-trough, and it condescribed and particularly pointed out in the l. Be it known that l, Ariens MoKl-mzin, a oil'iject of the King of Great Britain, residi convenientl and well known manner.

Similar numerals of reference indicate -corresponding parts in all the iignres ofthe dmwing.

ln the accompanying drawing, l represents the bed-plate, which is preferably supported in profiel' elevation by meansof the sup rts 2. o the hed-plate i. are attached or o rined integral therewith the sidehousingsB and 4. in the drawings I have 'illus` vtratedthe housings formed separate from the bedplate 1 and attached thereto by suitable bolts '5, but this is mechanical as the only object designed to be accomplished is to securelyconnect theside housings 3 and 4 tothe bed plate which may be done in any To the housings 3 and 4 aresecurely attached the brackets 6 by the bolts 7 or their equivalents, said brackets being for the pur ose'of'proriding supports for the trough orining bars S and 9 to which brackets said trouofh forming harsare connected by means ci? thetie-` plates 10; The trough forming hars 8 and 9 are substantially off the forni shown and are best illustrated in Fig. 151, and as illustrated the bars, at their fbrward ends are provided with theV straight or substantially straight-or plainfaced tops and the tops oi' said-bars gradually curved, said gradually curved faces being for the purpose of giving to the sheet .the desired and finished form of an eates-tr0ugh during the time and while -the plain sheet from which the eaves-trough -is formed passes or moves endwise over and upon the forming bars.' The sheets being fed or'moved upon, over and through the bars as hereinafter described. A

For the purpose of convenience in' placy ing the bars 8 and 9 in roper relative positionl with reference to t e adjacent ,parts of the machine, I prefer to forni the bars in two separate parts but 1 do not desire to be confined nor to limit myself in this respect ow ing to the fact that the saine object, and purposes so far as the formation of ear/'estrough is concerned can he. carried out With a single bar or former lbut when a s'inole.

bar or former is used .it necessitates the dis inantling a portion of the machine in case it is decided to employ different sized formers. l is well understood that it is necessary to p Ovide nieansi'or' the formation of various 5 sized eaves-trough, andby dividing,r the forsists, 1n the. novel arrangement hereinafter nier or using two parallel ha rs or forniers'they can be Aremoved from time to tune and ditferent sizes placed-,in position without the other advantage in dlvidin longitudinally is a slight a justment benecessityot dismantling the machine. An-

.the former tween the bars or. formers can be made b which adjustment the bars can be set with proper accuracy with reference to a given width of sheets from which a given sizeof trough is to be reduced. In the housings :E and 4 is proper y. journaled the power shaft l1.r which 'power shaft is preferably provided with the tight and loose wheels 12 and 13, which are of the ordinary construction. iTpon the power shaft 11 is securely mounted the gear wheel 14, which gear wheel, meshes with the gear Wheels 15 and 16. The gear wheel 14 by reason of its location will impart rotary motion tothe gear wheels 15 and 16 in the same direction and in order that the lower' tra in of gear wheels 1.7, 18, 19 and' 20 may all rotate in 'the same-direction .the intermediate'idle'rs 21 are-provided. Upon thershafts 22, 23, 24, 25, 26 'and '27 are' se curely 'mounted 'the lower. trainV of feed wheels 28, 29,. 30, 31, 32"and 33, and-,idirect-ly above the' lower train of feed'fyvlfeels -is located the. train of feed wheels't, 35,' 36

37. 3 8 and 39, said upper `and lower trainsof feed` wheels being for thepurpose of moving and forcing the sheet from which a trough is 'formed' over, upon .and through the former;

' lit 'wilibe understood that in o "r to e Y move the sheet it is necessaryA that thldlllhwer train 'of wheels all rotate in a' venilirec tion and the 'upper train 'of f wheels rog' tate Ain the opposite` directio and in order to' .provide for this opposite rotation fofthe upper and lower tramsoi feed wheels', the upper gear wheels40, 41,42, 43, Lietnd are provided. whichgear wheels are securely mo'unted upon theshafts`46, 4f?, 48, 49, 50 and 5l 'and' upon whc'h'shafts are mounted the 'upper feed wheels 34. 35. 36,37, 38 and '39. Tt Will he understood that in order that the sheets'inlay he properly gripped the |ieripheries"oilthe feed wheels should come in contact -with thc sheet of metal from which theeaves-trough is to be formed, and in order to provide for' this gripping or 'contactuporithc top andbottom sides of'the'- sheet the peripheries of the lower train of vfeed avheels must be exposed for proper contact.. with -the bottom or undersideof thel sheet and in order to provide' for this the 'forming bars or the former are' or is provid ed "with openings 52, through which openings the'upper portions of the lower train .Y of gear wheels arepassed.

For the purpose Vof giving o 'the -sheet from which thc'eaves-trough 's to be pro- Vduced the desiredftfrough forn the forming bars'S and 9 or the trough for; er is .formed of considerable length andtheforward. portion thereof provided' with-siibstantially a straight or plain faced part or portionwhich.

is gradually curved toward the rear or deto prevent the rupture of tie metal or in-v other words to'maintain the texture throughout the entire length of the trough and for this reason and at. the v same time better guiding and holding the. sheet the orm'ers.

should he ot' considerable length, but of vcourse the length may be varied at will and the same object accomplished. in the formation of eaves-trough it is necessary to proride the trough with a bead either upon one or both-of its edges and in' order to give the sheet an initial bend -or curve the disks 53 and 5t are provided, 'which disks are mounted upon the shafts 51 and 22' and their l'ieripheries formed of' such a shape that the proper initial bend pill'be imparted to the sheet. v

For the purpose. of forming the lip- 55 upon the inner-edge of a bead of an eavestrough the horizontal forming disks 56 and.

57 are provided, which forming disks are journaled upon the short studs 58 or securelymounted on said studs and the studs' journaled in the adjust-able plate. The peripherie's ofthe disk 56 and 57 are, formed endwise the lips will be formed; For the purpose of .preventinff the sheet of 'such a shape that as the sheetfisl moved from hucklmg'or springingt out of position .and at the .same time guiding .the sheet so that 'its edge will properly enter between the .disks 56 and 57 the guide plate 59 .is provided. which guide platelis securedto the hoi-:sing -t in any convenient and well known manner and the inner or' sheet contact endA of the guide plate 59 curved to. correspond substantially' with the curvature given the sheet bythe disks 53 and 54. After the sheet has passed the disks 56 and 57 the bead edge of the sheet. or the edge of the sheet upon which the head is to he formed passes into the` bead forming groove 60, which lbead forming groove is given' a radual curve or what might be more propery termed a twist surface. by which arrangement the bead is gradually formed in substantially the same manner that the body portion of the tro u,g his formed: that-is 'to sayformed'by degrees during the passage ot the sheet over,l upon and through the trough former pro er. -I

it is desired to form a bead upon bot edges 'of the trough then in that event a duplicate groove ($0 is formed upon both sides of the eaves -trough former proper, but these` grooves are duplicates only when two *bea-ds- 'are to be formed. l x Tt will be understood that there should bei iso amnestie- Corr no latera movement of the sheet dui-,ingji-Lhe time it is moved through the former, und in order to prevent any lateral movement fof tie sheet when but va single bea-d is to be formed one of the former hais or one side ot' tlie former as the case may be is provided with die guide flange 61, which guide flange is so located that it will hold a sheet so that. that portion of the sheet from Which the-head is-formed will be heldin proper re latiousliip withthe head :formingr groove 60.

It, will be .understood that when hea ds are. to be formed upon both sides ot' the t-nislied trough the opposite groove 60 will act as a guide as againstsfny lateral movement and of course the particular or single guide flange Gl is dispensed withand the second or head forming groove takes its place.. At

the forward end 'of the machine proper located thefeed table 62. which feed. table may bc ofany desired long h, but should be of sutieient length to proper-lj'vv support and hold the sheet.. The feed Vtable (iis prod vided with the adjustable guide bars-or flanges 63; which guide'langes are adjusted upon the-table sothattheir inner edves or faces will come in close-contact wiii the longitudinal edges of the sheet fromwhich 'an eaves'trougli is to be formed. 'I have illustrated the feed table y provided with the slots 64, which slots provide a means for adjusti 'o the guide bars 63 and when the guide hars .are brought into propel` adjustment ihevfare heldin fixed adjustment. by means oi the clamp holt 6 5.V

or the purpose of providing a means for adjusting' the -distancebetweenthe lower train of feed rolls and the'upper train,` the sh'atts upon which the upper train of feed rolls are mounted are-journaled in adjustable bem-'ings (36, which adjustment is made b the ordinary1 screw'threaded shafts 67, which 'shafts are preferably" provided with the hand wheels (38.

lt will he understood that owing `to the tact that the cui-rature of the trough former proper va ries it must necessarily follow that.`

the peripherics-,of the different sets of rolls must also-var 'win shape and curvature to correspond i'vith the change of curvature of :lio former. so that thc sheet of metalvwill be properly gripped at all points as it is fed or moved between the various sets of feed rolls.

.For the purpose of providing a means for adjusting the disks and 54 to diiliefeiit Y widths 'of sheets 'they are slidahljf mounted upoufthe shafts and heldin fixed adjust ment by the .set screws '70 or their equivalents. It is also necessary to provide adjustment for the :lipjformin disks 56 and 5T and in order to provide 'or this adjustment they are mounted upon the slidable plate T1, which plate located upon' the bracket :T2 and said bracket provided Withthc slots 'iT-3. It will be understood that the manner of adjusting the various disks -is mechanical and the means herein described forpmper adjustment may be varied without departing from the nature of the invention.

For the purpose of providing means for adjusting the feed rolls so that they will come in proper posit-ion with reference to the former they. are preferably slidably mounted upon the shafts, by which arrangement the proper adj ustment can made and so made' .tliait there IWill be no tendonqv of .the sheet to move other than parallel with the former.'
